The ET-R&D project is aimed at essential R&D tasks in preparation for a technical design of the Einstein Telescope, a 3rd generation, underground gravitational wave detector. While the basic design mostly relies on techniques well developed and tested for the advanced detectors, several aspects still require R&D with long lead times. We propose to target the most important of these topics in this ET-R&D project via 5 working groups (WGs).WG1 will explore how well astrophysical source models and GR itself can be tested with ET, and how much information on the dynamics of the universe can be extracted from the data. WG2 will collect long term seismic data for various candidate sites and develop methods for measuring the seismic motion which directly couples to the test mass motion, with the goal of developing subtraction techniques. WG3 will investigate properties of cryogenic optics essential for lowering detector thermal noise and providing good low frequency performance. The control of various interferometer degrees of freedom and noise correlations in the data of the three different ET detectors will be studied in WG4. WG5 will focus on overall project management.

ET-R＆D项目旨在为Einstein望远镜（第三代，地下引力波检测器）的技术设计做准备。尽管基本设计主要依赖于对高级探测器进行了良好开发和测试的技术，但一些方面仍然需要长时间的研发时间。我们建议通过5个工作组（WGS）在此ET-R＆D项目中针对这些主题中最重要的主题。WG1将探讨如何通过ET测试天体物理源模型和GR本身，以及从数据中提取有关宇宙动力学的多少信息。 WG2将收集各种候选地点的长期地震数据，并开发用于测量地震运动的方法，该方法直接将其与测试质量运动耦合在一起，目的是开发减法技术。 WG3将调查对于降低检测器热噪声并提供良好低频性能至关重要的低温光学元件的性能。将在WG4中研究对三个不同ET检测器数据中各种干涉仪自由度和噪声相关性的控制。 WG5将专注于整体项目管理。
